Description: The Cubs will use Pedro Strop at closer for the rest of the season, according to Carrie Muskat of MLB.com.

Insight: Kevin Gregg has had a surprisingly good season, saving 32 of 37 games and posting a 2.95 ERA in 58 innings. However, Strop is eligible for arbitration and the Cubs want to see what they have in him, and Gregg will be a free agent and probably won't return.

Insight: Strop has been automatic since coming over from Baltimore at the start of the month (0.00 ERA in eight appearances). It looks like the Cubs will be sellers at the deadline with Matt Garza also on the trading block.

Insight: Strop has a save in each of the last two games with Jim Johnson out with flu-like symptoms. While Johnson will be back soon, this should give some indication as to who manager Buck Showalter will turn to if Johnson were to go down for an extended period of time.
